There's a tough reality check on CO2: it's an oxide, and it's quite expensive to break.

I mean it's fine trying to save the planet and stop emitting co2, but so far, unless you do it by force, it's quite unlikely that anyone will really manage to convince people to do it, or find some miracle solution, or to organize something so that people make the efforts to avoid emissions.

We should just prepare to migrate north, grow food elsewhere, move away from hot regions, and more important: find more and more techs that allow every humans to protect themselves from heat.
